I think this needs to be pencilled up under "people with more money than sense".

Why would you add another 500kg to a 1000kg car?! Especially when said car has nothing going for it except its low weight and associated nimbleness. Who was that guy?! And why didn't he drive it around places where nobody knows or gives a flying fudge who he is?

Well, maybe this could serve as a good example that you can be too rich for your own good.
